Earlier this year, Apple submitted a spec to the IETF for live streaming multimedia content over HTTP, leading some to suspect that a live video protocol would soon be making its way to iPhone and iPod devices. With the new 3.0 version of the iPhone OS, that HTTP live streaming protocol became a reality, and while there were already a handful of live video apps on the iPhone, they’re presumably now a lot better.

This list is a round up of some of the live TV options available on the iPhone. Most of these apps work best over wifi (and a few won’t work at all over 3G), and generally live streaming is a big drain on battery life. Still, being able to catch up with live television or out-of-market broadcasts when you’re not near your TV is a great option for iPhone owners to have.

netTV (Free/$2.99)

Available in both free and paid options, netTV offers live streaming access to over 200 channels from around the world, including a larger-than-usual number of channels from the US. The quality is generally pretty good, though I did experience some issues when first connecting to a channel, and of course it varies from channel to channel (depending on the source of the video stream).

TVUPlayer (Free/$4.99)

TVUPlayer plays live TV for over 300 channels, though only a handful of channels broadcast at the right bandwidth to play well. Some of the video feeds come in choppy or with audio syncing issues (I actually couldn’t get audio to work at all), a result of the iPhone’s hardware limitations according to the developers. Still, the app offers an impressive line up of live international television channels, even if many of them are strange.

WorldView Live ($2.99)

WorldView Live isn’t exactly TV, but it is live streaming video. The app provides access to thousands of live web cams from around the world. Only a handful (about 60, according to the developer) are actually live video, but the app does offer an interesting, if voyeuristic, view of the world for armchair travelers.

BONUS: Television ($2.99)

The $2.99 Television application isn’t live TV, but it offers access to an impressive line up of television video catch-up services. The app, which only works over wifi, lets users watch on-demand video from HBO, ESPN, NBC, FOX, CBS, Comedy Central, CNN, Sky and more.

FRANCE 24 LIVE (Free)

The live application from France’s channel 24 news offers live, video-on-demand streaming from the network in French, English, and Arabic over wifi, 3G, and even Edge! Of course, the video will be pretty choppy and low quality over Edge, but it’s unique among live video applications for even offering that option at all.
